A modern architectural icon nestled in the coveted Santa Monica Canyon, 721 Adelaide Place exemplifies the visionary design of Ray Kappe, FAIA, whose renowned work defines the "apotheosis of the California House." This LEED Gold Certified residence seamlessly blends sculptural form, environmental sensitivity, and a profound connection to nature. Spanning nearly 5,000 square feet, the home is intentionally designed to celebrate volume, light, and awe-inspiring ocean, coastline, and mountain views. Upon entering, a dramatic two-story foyer sets an impressive tone. Here, a sleek floating staircase serves as a sculptural centerpiece, floor-to-ceiling glass walls allow radiant natural light to fill the space, and artisan craftsmanship is on full display with the use of wood, steel, and stone. Open-concept living and dining areas are positioned around a two-way Corten steel fireplace with a marble hearth, creating a sophisticated and inviting ambiance. The Arc Linea chef's kitchen is a showpiece of modern design and functionality, featuring a Crocodile Caesarstone backsplash, a butler's pantry, and professional-grade Wolf and Miele appliances. Retractable glass walls open the living areas to an outdoor sanctuary complete with covered and uncovered patios, a sparkling pool, an infinity-edged spa, an outdoor shower, and panoramic ocean and mountain views that elevate entertaining. Upstairs, the primary suite offers a retreat of exceptional comfort and style. Here, a private deck captures breathtaking views, while the custom-designed walk-in closet and luxurious ensuite--featuring dual vanities and an ocean-view shower--enhance daily living. Three additional bedrooms, including one on the main level, each open to private terraces, complemented by a versatile office and lower level media room. An expansive rooftop deck with a firepit crowns the home, offering a spectacular vantage for sunsets over the Pacific. Advanced smart home tech, including Control4 home automation, integrated surround sound, a Generac generator, and solar panels, ensures convenience and efficiency. Other notable features include mature landscaping that envelops the property in serenity and seclusion, a two-car garage, and automatic driveway and pedestrian gates. Supremely situated in one of Santa Monica's most desirable enclaves, this home captures the essence of California coastal living--mere moments from the beach, world-class dining and shopping along Ocean and Montana Avenues, and just minutes from the Riviera Country Club. 721 Adelaide Place stands as a testament to timeless modernism and coastal refinement, a rare architectural achievement where design and lifestyle converge.
